  • Can send 1 Gem-Knight monster from your Main Deck or Extra Deck to the Graveyard to inflict 500 LP damage per Special Summoned monster on the Field.

  • Gem-Knight Lapis must be 1 of the Fusion material.
  • Weak DEF stats.
  • Can only be Special Summoned once per turn.


Fusion Support

You are most likely required to use Polymerization to Fusion Summon, therefore you can use these cards to support your Fusion actions. Fusion Recycling Plant can recycle 1 fusion material monster to your hand, and also search for Polymerization from your deck. King of the Swamp can be treated as 1 fusion material required for Fusion Summon, and at the same time it also can be used to search 1 Polymerization from your Deck. Fusion Sage can search 1 Polymerization from your deck. Defusion is a powerful follow-up card when you attack with your Fusion monster, as it can dissolve the Fusion monster to resummon the Fusion materials from your Graveyard, enabling you more attack options. Fusion Reserve allows you to add 1 of the Fusion materials listed on the Fusion monster to your hand, and add 1 Polymerization from your Graveyard to your Hand.


You can first use Gem-Knight Lady Lapis Lazuli’s effect to inflict LP damage to your opponent, then include Gem-Knight Lady Lapis Lazuli with another 2 Gem-Knight monsters to Fusion Summon Gem-Knight Master Diamond, and replicate Gem-Knight Lady Lapis Lazuli’s effect from your Graveyard, to further inflict LP damage to your opponent.

Special Summon

These are some of the cards to further increase the number of Special Summoned monsters on your Field.

Hey Moona!
Lapis Lazuli, give me!
The appearance of this card really hints at the real identity of El-Shaddoll Construct, eh?

It’s actually not, as long as Master Diamond remains higher than 1 it still remains possible. It’s just become a good bit harder

At first i kinda hate this deck but then i realized that i already fell for it
Can this deck work with magnet warrior since they both rock-type??

There's not really any synergy there. Using Delta as Fusion Material for Zirconia is about as deep as the combos go. You'd be better off focusing on one or the other, combining them would make both aspects noticeably worse.

Sometimes you can't just mash two decks together just because they have the same Type.

Jurrac and Evolsaur are both FIRE Dinosaur-Type archetype, but they focus on two different things (Jurrac is beatdown using high level main deck monsters, while Evolsaur is Rank 4 Xyz), that you can't just mash them together and think they'll work together somehow.
The gem knights deck needs gem armadillo for an extra +1
🔥 fur hure in 2 turn lol.
Is this combo possible?
1. Use her effect to send lazuli to the grave. Add lapis back to the hand.
2. Banish another gem knight in the grave for gem knight fusion
3. Fusion summon master diamond using lapis in the hand and lapis on the field.
4. Burn them again
